IT pulse transformers are designed to offer

you galvanic isolation for transformer coupled

gate drives. The IT series provides negligible

delays and the possibility of voltage scaling.

They are available with single or double

secondary winding for multiple gate drives.

Choosing the IT product line brings you the

rapid availability of a standard gate drive

transformer. A wide selection on turns ratio,

ignition current and voltages are designed to

offer you the desired standard product.

... Explanations: – rise time at given load resistor R and 70% of the output pulse height. – primary inductance measured at 1kHz (secondary coile open). – L str stray inductance measured at the secondary side, short circuit at the primary side. If there are several secondary coils only one at the time is connected (measuring frequency 10kHz). ...
